The processing of porous architectures based on Layered Double Hydroxides (LDH) is reviewed. Especially, a focus was put porosity in nm and μm ranges that can be prepared via various post-treatments templating techniques for the enhancement original properties. A challenge toward desired control structural ordering as well crystal growth LDH. present review paper mainly dedicated to summarizing...

The majority of modern anticancer approaches target DNA/protein targets involved in tumour-cell proliferation. Such approaches have a major drawback, as nonproliferating cancer cells remain unaffected and may cause relapse or remission. Human coatomer protein complex I (COPI) subunit ζ (Copζ), a component of the coat protein involved in cell apoptosis and intracellular trafficking, has recently...

Recombinant techniques are routinely used for the preparation of protein samples for structural studies including X-ray crystallography. Among other benefits, these methods allow for a vast increase in the amount of obtained protein as compared to purification from source tissues, ease of purification when fusion proteins containing affinity tags are used, introduction of SeMet for phasing, and...

The importance of sample homogeneity and purity in protein crystallization is essential to obtain high-quality diffracting crystals. Here, in an attempt to determine the crystal structure of thioredoxin 1 from whiteleg shrimp Litopenaeus vannamei (LvTrx), we inadvertently crystallized the hexameric inorganic pyrophosphatase of Escherichia coli (E-PPase) from a non-homogeneous sample product dur...

Crystalline organic solids are ubiquitous as either final products or as intermediates in the specialty chemical, pharmaceutical, and home & personal care industries. Virtually all small molecular weight drugs are isolated as crystalline materials, and over 90% of all pharmaceutical products are formulated in particulate, generally crystalline form. Crystalline chemical intermediates, such as a...
